in order to take out the rear interior quarter panels, you have to start taking all the other stuff out from the inside of the back starting with the piece at the very back of the hatch working your way around. all they have are push clips on the inside, but they're set up in such a way that you have to take out one before the other so you wouldn't be able to see the points of attachment. same thing with the c pillars, but you will have to take the top bolt of the seatbelt out of the frame to release that part, i think it's either a 14 or 15mm bolt. it's all relatively easy for those parts, just time consuming. as for the airbag, you've got me there, i dunno, if you remove the cables for the battery it should disable it so that it will not deploy.
